Operationalising sustainability has proven difficult because the concept is ambiguous and fraught with contradictions. In response, sustainability indicator systems to characterise and measure sustainable development have been developed globally. The focus of this article is on how indicators function as an instrument of policy to enhance achievement of environmental and sustainability policy in Australia at national scale. In theory, by integrating information from the environmental, social and economic domains and then feeding knowledge to a wide range of policy sectors, sustainability indicator systems may facilitate cross-agency and -portfolio connectivity. Key characteristics of the various sustainability indicator systems developed to inform policy at the national level are described, noting the diverse approaches to indicator development in Australia. The structural relevance of indicator systems to the mechanisms of policy and institutions in Australia is discussed, and corresponding issues of institutional fit are analysed . 相似文献

As the number of smartphone users have increased worldwide, research on the usage of the smartphone has received scholarly attention. However, different results were found in previous studies in different contexts. The main research question is whether adopting smartphones by students improve learning or generates interference. The purpose of this study is to examine the usage of smartphone among university students in Pakistan. Using a survey approach, data were collected from different universities/colleges of Karachi, Sindh, Pakistan. total, 585 entries was analyzed using SPSS 21.0 and AMOS 21.0 software. Results of analysis, validated most of the hypothesis showing the intention of Pakistani students towards smartphone usage for academic purpose. In addition, findings confirm that students' self‐efficacy related to a smartphone works as a moderating role of intention to use a smartphone for learning and actual usage of the smartphone. The current study has several implications in terms of smartphone usage and student academic performance. Limitations and implications of the study are also discussed in the last section. 相似文献

Pericardial defects are rare in childhood and outcome is usually benign. Patients may be asymptomatic, but chest pain, emboli, arrhythmia, and sudden death have been described in the literature. We report the case of a 12-year-old boy who suddenly died after mild exercise. A left-sided pericardial defect with a diameter of 8 cm was detected on medico-legal autopsy. 相似文献

This study presents a wavelet analysis of resultant velocity features belonging to genuine and forged groups of signature sample. Signatures of individuals were initially classified based on visual human perceptions of their relative sizes, complexities, and legibilities of the genuine counterparts. Then, the resultant velocity was extracted and modeled through wavelet analysis from each sample. The wavelet signal was decomposed into several layers based on maximum overlap discrete wavelet transform (MODWT). Next, the zero crossing rate features were calculated from all the high wavelet sub‐bands. A total of seven hypotheses were then tested using a two‐way ANOVA testing methodology. Of these, four hypotheses were conducted to test for significance differences between distributions. In addition, three hypotheses were run to provide test for interaction between two factors of signature authentication versus perceived classification. The results demonstrated that both feature distributions belonging to genuine and forged groups of samples cannot be distinguished by themselves. Instead, they were significantly different under the influence of two other inherent factors, namely perceived size and legibility. Such new findings are useful information particularly in providing bases for forensic justifications in establishing the authenticity of handwritten signature specimens. 相似文献

Forensic application of carbon isotope ratio measurements of honey and honey protein to investigate the degree of adulteration with high fructose corn syrup or other C4 plant sugars is well established. These measurements must use methods that exhibit suitable performance criteria, particularly with regard to measurement uncertainty and traceability – low levels of adulteration can only be detected by methods that result in suitably small measurement uncertainties such that differences of 1‰ or less can be reliably detected. Inter-laboratory exercises are invaluable to assess the state-of-the art of measurement capabilities of laboratories necessary to achieve such performance criteria. National and designated metrology institutes from a number of countries recently participated in an inter-laboratory assessment (CCQM-K140) of stable carbon isotope ratio determination of bulk honey. The same sample material was distributed to a number of forensic isotope analysis laboratories that could not participate directly in the metrological comparison. The results from these studies have demonstrated that the majority of participants provided isotope delta values with acceptable performance metrics; that all participants ensured traceability of their results; and that where measurement uncertainties were reported; these were fit-for-purpose. A number of the forensic laboratories only reported precision rather than full estimates of measurement uncertainty and this was the major cause of the few instances of questionable performance metrics. Reporting of standard deviations in place of measurement uncertainties is common practice outside metrology institutes and the implications for interpretations of small differences in isotopic compositions are discussed. The results have also highlighted a number of considerations that are useful for organisers of similar inter-laboratory studies in the future. 相似文献
